Carolina Wild Petunia

Carolina Wild Petunia, Ruellia caroliniensis, is the perfect native flower to replace the invasive Mexican petunia. This long-lived perennial reaches 1 to 2 1/2 ft tall and is a wonderful ground cover. The gorgeous lavender flowers last only a day but this wild petunia blooms from early spring through fall in sun or shade.
Look for Carolina wild petunia seeds at Native nurseries and FNPS plant sales. Plants that are a few years old can be propagated by division. Plant Carolina Wild petunias in your garden to attract pollinators. White Peacock and Common Buckeye butterfflies use the plant as a larval host.

Sunshine Mimosa

Sunshine Mimosa
Are you looking for a native groundcover that attracts pollinators and looks beautiful all year long? Sunshine mimosa (Mimosa strigillosa) is a fast-growing ground cover with adorable pink puffballs. It’s sometimes called “powderpuff mimosa”.
A popular trait of sunshine mimosa is the nastic response. When the leaves are touched it alters the turgor pressure in the extensor cells and causes the leaves to retract. When this happens potassium and chloride molecules leave the cells. This leads to osmosis, a mechanism that occurs when water flows towards the higher salt concentration. In this case, water flows out of those cells and reduces the turgor pressure so the leaves will close.
Do you have sunshine mimosa in your yard? What is your favorite quality of this plant?
